Over the past 6 months, my skin has become increasingly "itchy". It started on my legs and has ultimately found it's way to my scalp.
Its noticable after showers (med. in temperature), water on skin will sometimes make it itch. After an "outbreak" about 20 minutes later it stops itching and all looks/feels fine.
It appears to be the hair follicle that is raised and irritated and it loks like several small bumps in patches.
I can not issolate what casues the outbreak.

Hives are red, itchy welts or swellings on the sk<span style = 'background-color: #dae8f4'>in</span> that often come in clusters. They sometimes have a light red or pale center surrounded by a darker red area around the borders -- a marking resembling tiny bull's eyes -- but may simply look like large red circles. in doctor speak, hives are known as "urticaria."
Hives can appear anywhere on the body, cropping up either inone small area or covering large patches of skin. They most often occur as part of an allergic reaction.

If exercise is nothing new for you, it's more likely a dry sk<span style = 'background-color: #dae8f4'>in</span> issue
Dry sk<span style = 'background-color: #dae8f4'>in</span>. Since you didn’t mention any other symptoms, it could be that dry skin is the culprit. Are you walking outside or inside? Often, dry weather conditions can cause or exacerbate dry skin. If this is the case, using lotion, investing in a humidifier, and staying hydrated can all help combat dry skin.
Skin irritation. Have you switched detergents, started using a new lotion, or are you using a new soap?

Hello,
It can be due to allergies, hives, sweat dermatitis or <span style = 'background-color: #dae8f4'>heat</span>rash . Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken.

For three months or so I have been experiencing itchiness on my neck (not the entire neck) and where its itchy I see like a red patch and hot, I can feel a roughness on that area but not bumpy. I have taken benadryl but dont seem to help. Can you please tell me what that is? it's driving me nuts! ugh.

My sk<span style = 'background-color: #dae8f4'>in</span> breaks out in a burning, itchyrash, sometimes with blister-like welts when exposed to heat or cold. Does not have to be sun (although the sun will do it). Just BEinG hot doesn't do it (I can be involved in physical activity that might make me sweat and not break out). Just a few minutes in the sun makes my arms and upper legs break out. If I cross my legs or arms for a few minutes I break out in the area my skin was touching.

Cholinergic urticaria is a subcategory of physical urticaria ( hives) that is a sk<span style = 'background-color: #dae8f4'>in</span>rash brought on by a hypersensitive reaction to body <span style = 'background-color: #dae8f4'>heat</span>. Symptoms follow any stimulus to sweat such as exercise (sometimes called exercise-induced urticaria), heat from the sun (which could also indicate solar urticaria), saunas, hot showers.
The visible hives (sometimes called heat bumps) appear as a multitude of small 2-3 mm welts typically surrounded by patches of red skin.

Miliaria is a sk<span style = 'background-color: #dae8f4'>in</span> disease marked by small and itchyrashes. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season."( http://en.wikipedia.org/wiki/Miliaria). The sweat rash may persist for quite sometime and may need topical medications like corticosteroids to help resolve it.
If it does not appear in other areas of the body and seems to be present and localized inone definite area, then a diagnosis of a sweat rash is likely.

Hello, I have a question that I need a second opinionon, for the past 5 years Ive had frequent ( ever two, months or so) outbreaks of red patches on the sides and bottoms of both feet, sometimes at the same time, sometimes not.

Hi,
I've been having a problem with itchysk<span style = 'background-color: #dae8f4'>in</span> and not just inone specific area. I've had it on my legs,nose,back,face in general. I'm justwondering what could cause the skin to become itchy the only thing i could think of is my long hot showers and exposure to hot furnance heat other than that i dont know anything i do differently..

Hi,
This sounds like a heatrash or milaria , though nothing can be said with surety without having a look at the lesions.
'Miliaria (miliaria rubra, sweat rash or prickly <span style = 'background-color: #dae8f4'>heat</span>) is a sk<span style = 'background-color: #dae8f4'>in</span> disease marked by small and itchy rashes. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season. '
'The prevention and treatment of miliaria primarily consists of controlling heat and humidity so that sweating is not stimulated.

I've had these little bumps on my neck a couple of years now there very small and looks like they are filled with fluid. It looks just like a <span style = 'background-color: #dae8f4'>heat</span>rash, thats what i thought it was at first. It itches very bad when i get hot. It was'nt that many before but now it's spreading all over my neck and itches more often. It has become very noticeable.

At first he thought it was a dandruff that has just moved down. I never have flakes, however, I do have itchy scalp. The <span style = 'background-color: #dae8f4'>heat</span> allergy makes sense. He also prescribed Doxyclycline which has done nothing after being on it for almost two months. The only other medication I'm on, besides what he has prescribed for the condition listed above, is Estradiol 1mg and Prometrium 100mg. I wondered if that was causing it when it comes through my sweat glands. He has not given me any antiallergic medicine.
